PURPOSE: Provided is a high viscosity Ag paste composition for forming a fine accurate battery, which can be applied to a calcination process with less than 600deg.C and is excellent in a printing property and economical and friendly to environment. The fine battery produced by using the composition is also provided. CONSTITUTION: The high viscosity Ag paste composition contains: 60-80wt% of Ag powder having an average particle size of 0.5-3 micrometer; 1-10wt% of at least one inorganic binder selected from the group consisting of lead borosilicate frit, bismuth borosilicate frit, B2O3·SiO2·MO and B2O3·SiO2·M'2O, wherein M and M' are divalent metal ions; 0.001-1wt% of at least one stabilizer selected from the group consisting of a benzotriazole, an ascorbic acid, and a phosphoric acid, a phosphorous acid, or a salt thereof; 15-35wt% of an alkali-soluble negative photoresist composition for dispersing a fine conductive powder, which contains 30-70wt% of an acrylate copolymer for a photoresist, 10-40wt% of a photopolymerizable monomer, 0.5-10wt% of a photopolymerization initiator, 0.1-10wt% of an antifoaming agent, and 0.1-10wt% of a leveling agent. And the fine battery is produced by using the Ag paste composition.
